Routing 800-volt DC high-power bus bars through composite aircraft cabins adjacent to passenger seating introduces acute fire and electrocution hazards. We present 3D CAD automated Zonal Safety Analysis frameworks.
Spatial analysis tools scan the complete digital mock-up, verifying that 800V conduits maintain at least 200 mm clearance from flight control signal harnesses and combustible cabin trim materials.
Simulating electrical arc-fault plasma bursts demonstrated that localized ceramic thermal barriers contain 15,000°C arc temperatures without puncturing carbon fiber cabin bulkheads.
